I have a 75 gallon reef tank that is about two months old and I have had no problems up until now and I have lost three (maybe four) fish in the last four days.
Fish lost:
1 orchid dottyback - I had this fish for about six months and it always did well with tank changes as I've upgraded in size and it also seemed to do great through nitrate and nitrite spikes as my tanks have gone through their cycle.
1 blue damsel - this one was most shocking as I've had this fish for a few months and he was always one of my heartiest eaters.
1 golden banded butterfly - this was only about a week and a half into the tank and I couldn't get him to eat frozen foods so unfortunately I think his death had to do with him not acclimating to the new tank very well.
1 blue tang (this is a maybe as I haven't located him yet or actually seen him dead but I cannot find him)
Water Parameters
75g display tank
40g sump with protein skimmer and refugium
Ph= 8.1
Nitrite= 0ppm
Nitrate= 0ppm
Ammonia= 0ppm
Phosphate= 0ppm
KH= 8 degrees / 140ppm
Calcium= 440ppm
Other tank inhabitants:
1 head of toxic green hammer euphyllia
2 heads frog spawn euphyllia
2 heads branching torch euphyllia
1 yellow tang
1 maroon clown
1 orange clown
1 1.5" Green crab
1 cleaner shrimp
5 medium sized hermit crabs
1 sand sifter starfish
1 small acrophyllia
1 superman Cyphastrea
2 heads of green candy cane coral
1 small frag of green star pollup
75lbs live rock
White sand substrate
I would have expected high phosphates or ammonia but neither were found and I did double check each test to be sure. I also expected my corals to suffer before my fish did but it seems to be backwards. Any ideas what could be happening to cause my fish to die? The fish who have died have not had broken or cut up fins or anything that would lead me to believe they were killed off by another tank inhabitant. Please help, any and all suggestions are welcome!
